Specification of Letters Patent.

"M ews-'15 19 2- Application filed January 22, 1921. Serial No. 439,273.

the following is a specification.

This invention relates to an apparatus designed to be mounted at a convenient point in the flushing conduit for refuse from mining. The invention is based upon the idea to use air under pressure or water under pressure for assisting the flow in the flushing conduit if said conduit has to be conducted for long distances either in horizontal direction or in an upwardly inclined direction.

In order that the invention may be clearly understood, I shall proceed to describe the same with reference to the example of construction shown in the accompanying drawings, wherein Fig. 1 is a side elevation of the auxiliary device, the main tube being shown in section.

Fig. 2 is a plan View of the Fig. 1, and

Fig. 3 is a cross-section of Fig. 1.

Fig. 4 shows a modified form of construction in side elevation.

Fig. 5 is a cross section of Fig. 4.

The auxiliary apparatus shown in Figs. 1, 2 and 3 is tube-shaped and composed of an upper part 1 and of a lower part 2 which are riveted or welded together to form a tube. The upper part 1 has its edges bent inwardly in spiral-shape so that two pipes 3, 4 of small cross section are formed. The edges of the upper part 1 of the tube are arranged so that at either side a slot 5 is formed. The tube is thus divided into four chambers of which the upper one 6 is designed to receive a pipe 7 for the supply of pressure air or of water under pressure.

Spraying pipes 8 branch off laterally from the pipe 7 reaching into the slots 5 of the tubes 3 and 4:. Tubular connecting pieces 9 and 10 whose cross sections correspond with the cross sections of the tubes 3 and 4 are arranged at the two ends of the apparatus.

The operation of the apparatus is as fol lows:

Air under pressure or water under pressure is supplied to theapparatusbefo'rethe flushing is started. When the flushing has been started properly air under a pressure of 2+7 atm.-is admitted. The pressure passes from the chamber 6 through the slots 5 and rotates the flushing material. -As the same pressure or even a higher pressure comes from-the-spraying pipes 8 and as these-spraying pipes are situated in the direction of movement. of the flushedv materlal this material which is strongly-rotating is simultaneously pressed forward. .The

pressure is not only lllllllZQClifOI moving the material forward andrfor rotating the same but also for ensuring an intimate mixing of said material. p It is particularly important that material conveyed byflushing which enters the apparatus through the tubular connecting piece 9 is divided into twofiows of reduced cross section when getting into the tubes 3 and 1 whereby the speed of the material is in-' creased.

If however instead of the tubular chambers 3 and 4 of reduced cross section one large. passage is required, this being preferable with wide spreading material such as slate or thelike, the form of. construction shown in Figs. 4 and 5 is preferably used.

The apparatus shown in Figs. 1 and 5 consists of a-tubular. body 11 of essentially cylindrical shape, designed to be inserted in of tubular body 11. The chamber is closed by a removable lid 13 which has a tubular.

socket let to which the supply for the pres- 7 sure air is to be connected. Channels. 15 which are preferably arranged directly in the wall of the tubular body 11 connect the chamber 12 with said tubular body. channels stand at an angle with regard to the direction of movement of the material conveyed through the tubular body 11 so that they exert a rotating and pushing effect upon the material in the direction of flow. This apparatus permits therefore to assist the flushing flow to overcome horizontal or inclined lengths.

As the apparatus is closed tightly it is impossible that the pressure air escapes. without being utilized.

I claim 1. Apparatus to be inserted in flushing These 1 radially projectin from said pipe and conduits for refuse from mining and designed to increase the speed of flow and to help to get over long horizontal orinclined parts of the tubular closed conduit comprising in combination with the flushing conduit a tubular body to be inserted in said flushing conduit composed of tWo parts connected by riveting or Welding, the edges orthe upper part being curved inwardlyto form tubular conduits for the material to be conveyed by flushing, said tubular conduits being of small cross section and said edges being-not in contact With the inner Wall of said upper duits connected With said source of air or Water under pressure, and spraying pipes terminating tangentially and obliquely into said slot-sot said tubular conduits.

2. An apparatus to be inserted in flushing conduits for refuse from mining and designed to increase the speed of flow and to help to get over long horizontal or inclined parts of the tubular closed conduit comthe tubular body Whose orifices stand tangentially and obliquely to the flow of material in said tubularbody and designed to connect said chamber with the source of fluid under pressure, substantially as described and shown and for the purpose set forth.

In testimony whereof I affix my signature-in presence of two Witnesses.
